fix(mobile): sync img placeholder colors with current text color

[hejsztynx]

Summary

The inline image's placeholder colors were inconsistent across all platforms:

• web: the color matched the current text color (correct)
• iOS: the color was fixed
• Android: the color was fixed

Test Plan

Create an inline image with an invalid url to create a img placeholder. Next adjust the EnrichedTextInput style prop, with a changed color. Notice the updated color on the placeholder.

🟡 Changes recommended

Android AsyncDrawable’s placeholder path mutates drawable/state from a background thread (and doesn’t set placeholder bounds), which can cause incorrect rendering and thread-safety issues.

Once you've addressed the issues Copilot identified, you can request another Copilot review.

Pull request overview

This PR updates the iOS and Android implementations so inline image “broken/invalid” placeholders inherit the current text color, matching the intended behavior seen on web.

Changes:

• iOS: updates attachment image view tinting to follow the current configured primary/text color during attachment layout updates.
• Android: plumbs a “current text color” value through span factories and image span creation, and adds refresh logic to update existing placeholder tints when the text color changes.
• Android: adds placeholder-tint support to both async (network) image drawables and static fallback placeholder drawables.

This was caught by Copilot. Previously loadPlaceholderImage which mutates AsyncDrawable internal state, could be run from a secondary thread. This may lead to some state desynchronization, so we delegate it to the main thread, just like we already do few lines above
